The recent Under-20s World Cup only accentuated his star potential and at just 19 his mentality is a particularly impressive attribute.

It is clear that he will have no problem settling into Martinez’s new-look side and he will join up with the squad when they embark on their pre-season tour of the United States.

Cartlidge said: “He only turned 19 in March and throughout his playing career, has played the older groups, it’s just how it’s been for him.

“He’s extremely ambitious and confident, always wanting to improve and clearly wants to be the best in the world.

“I don’t think anyone can criticise him for this, it’s just his attitude.

“He’s unique in this sense, as we’re fed so much about humble, introvert Spanish footballers.

“Deulofeu’s a bit special in character and style, I think he’s good enough to handle life on and off the pitch – albeit with some help from Martinez and friends (Luis Alberto, Joel being around him).”

Deulofeu found first-team opportunities sparse as a result of Barcelona manager Tito Villanova’s health concerns last season.

Despite the four-time European champions desire for him to remain in the Spain this season, the player himself is of the belief a move elsewhere is the best place for him to develop.

“Eusebio (Barca B head coach) isn’t a coach that fills the player with confidence so it’s understandable he wants to play elsewhere,” Cartlidge explained.

“Deulofeu shouldn’t be making this move, in a sense, because he should be learning at a Barcelona with structure. Right now, there isn’t one that he feels can make him a better player. That’s where Everton comes in.”

The Spanish Under-20 International is likely kick off his Blues career when the side face Juventus in AT&T Stadium in San Francisco on August 9.
